Abstract

A problem to be solved is, in a thin type display panel with few bezel sections, improving strength in a curved part or adhesion between substrates. A display panel includes a first substrate having flexibility, a second substrate having flexibility, a sealant for adhering the first substrate and the second substrate, and an adhesion section for adhering the first substrate and the second substrate arranged on the inner side or outer side of the sealant, wherein a curved part is arranged on the inner side of the sealant, and the adhesion section is arranged in the curved part or in the vicinity of the curved part.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A display device comprising:
 a first substrate having flexibility and having a plurality of signal lines and a plurality of thin film transistors; 
 a second substrate having flexibility and having a color filter; 
 a sealant formed along an outer periphery of the second substrate and adhering the first substrate and the second substrate; 
 a liquid crystal layer sealed by the first substrate, the second substrate and the sealant; 
 an adhesion section for adhering the first substrate and the second substrate arranged on an inner side or outer side of the sealant; 
 a first polarizing plate disposed overlapping the first substrate; 
 a second polarizing plate disposed overlapping the second substrate; and 
 a backlight disposed along the first substrate and having a first surface on the first substrate side, a second surface serving as a side surface and a third surface serving as a back surface of the first surface, 
 wherein 
 the first substrate and the second substrate have a display portion, a bending portion and a back-surface portion, 
 the display portion opposes the first surface of the backlight, 
 the bending portion opposes the second surface of the backlight, 
 the back-surface portion opposes the third surface of the backlight, 
 the adhesion section is arranged in the bending portion, and 
 the first polarizing plate and the second polarizing plate are in contact with only the display portion and are not in contact with the bending portion and the back-surface portion. 
 
     
     
       2. The display device according to  claim 1 , wherein the adhesion section is a resin structured body. 
     
     
       3. The display device according to  claim 1 , wherein the adhesion section is formed from a material having a higher moisture permeability or oxygen permeability compared to the sealant. 
     
     
       4. The display device according to  claim 1 , wherein the adhesion section extends along an extension direction of a curved axis of the bending portion. 
     
     
       5. The display device according to  claim 1 , wherein a plurality of adhesion sections is arranged in an extension direction of a curved axis of the bending portion or in a direction intersecting the extension direction. 
     
     
       6. The display device according to  claim 1 , wherein a length of the adhesion section in an extension direction of a curved axis of the bending portion is shorter than a length of the sealant in the extension direction. 
     
     
       7. The display device according to  claim 1 , wherein the adhesion section is formed from a resin having thermosetting properties. 
     
     
       8. The display device according to  claim 1 , wherein the adhesion section is arranged further to the outer side of than an inner end of the bending portion and on an inner side of the sealant, and a distance between the adhesion section and the inner end of the bending portion is shorter than a distance between the adhesion section and the sealant. 
     
     
       9. The display device according to  claim 1 , wherein bending rigidity in the bending portion is lower than bending rigidity further to the inner side than the bending portion. 
     
     
       10. The display device according to  claim 1 , wherein the sealant is formed across the display portion, the bending portion and the back-surface portion. 
     
     
       11. The display device according to  claim 1 , wherein a terminal area is formed between the end of the first substrate and the sealant in the back-surface portion.
